Magnaflow 49294 Features:

Keep the check engine light off with MagnaFlow OEM Grade Direct-Fit Catalytic Converter 49294. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed specifically for the 2003-2006 Nissan Sentra and interchanges with OE parts 208A0-8U325 and 208A0-8U525. Avoid potential exhaust leaks by using the included gaskets to get a proper seal.
